With technological advancements, the types of backlight lenses have increased, including different types of backlight sources such as EL, CCFL, and LED.

[0020] like Figure 1As shown, this utility model provides a multifunctional integrated lens structure, including a light-emitting element 1, an optical carrier 4, a curved surface element 2 for beaming light, several conical elements 3 for total internal reflection and collimation of scattered light, and several V-shaped teeth 5 for uniformly diffusing light. The several conical elements 3 are staggered on the optical carrier 4. The light-emitting element 1 is located at the tip of the conical element 3. The curved surface element 2 is embedded inside the conical element 3 and located at the light-emitting element 1. The several V-shaped teeth 5 are horizontally arranged at the bottom end of the optical carrier 4. The light emitted by the light-emitting element 1 passes sequentially through the curved surface element 2, the conical element 3, the optical carrier 4, and the V-shaped teeth 5.

[0021] As one embodiment of this utility model, the curved surface of the curved component 2 covers all the light range emitted by the light-emitting component 1.

[0022] In another embodiment of this utility model, when the light emitted by the light-emitting element 1 is perpendicular to the curved surface of the curved element 2, the light does not refract and passes perpendicularly through the conical element 3 and the optical support element 4.

[0023] In another embodiment of this utility model, when the light emitted by the light-emitting element 1 is not perpendicular to the curved surface of the curved element 2, the light is refracted and reflected as perpendicular light when it touches the inner wall of the conical element 3, passing perpendicularly through the optical carrier element 4.

[0024] In another embodiment of this utility model, when light reaches the V-shaped tooth 5, it is refracted when it passes through the inclined surface of the V-shaped tooth 5. When it encounters the outer surface of other V-shaped teeth 5, it is reflected outward and refracted inward.

[0025] In another embodiment of this utility model, the height of the V-shaped tooth 5 is in the range of 0.01mm-0.05mm.

[0026] In another embodiment of this utility model, the width of the V-shaped tooth 5 is in the range of 0.001mm - 0.003mm.

[0027] In another embodiment of this utility model, the light-emitting element 1, the optical carrier element 4, the curved surface element 2, the conical element 3, and the V-shaped tooth 5 are integrally formed.

[0028] This invention provides a multifunctional integrated lens structure for use in the backlight assembly of projection products such as vehicle head-up displays (HUDs) or automotive intelligent voice assistants (VPAs). This single lens simultaneously addresses the practical needs of collimation, uniform light distribution, and brightness enhancement.

[0029] The light-emitting element 1 can be an LED lamp. The LED beads of the light-emitting element 1 serve as a point light source, emitting light in a conical diffusion pattern. When the light comes into contact with the curved surface element 2, and the incident angle is perpendicular (or nearly perpendicular) to the curved surface element 2, refraction will hardly occur. Therefore, the curved surface element 2 is designed to ensure that as much light as possible is incident perpendicularly (or nearly perpendicularly), which can minimize light loss. At the same time, in order to receive as much light as possible from the light-emitting element 1, the inner curved surface of the curved surface element 2 needs to cover the entire light range of the light-emitting element 1, which can achieve a light-binding effect and increase light transmittance.

[0030] When the light emitted by the light-emitting element 1 is perpendicular to the curved surface of the curved element 2, the light path will not refract and will pass perpendicularly through the conical element 3 and the optical support element 4 before entering the V-shaped tooth 5. When the light emitted by the light-emitting element 1 is not perpendicular to the curved surface of the curved element 2, the light will refract, and the refracted light path will be emitted towards the inner wall of the conical element 3. Upon contact with the inner wall of the conical element 3, reflection will occur, causing the light path to change from oblique to perpendicular. The conical element 3 acts as a collimator, straightening the refracted light so that it can enter the V-shaped tooth 5 perpendicularly. Since the light emitted by the LED beads diffuses in a conical shape, the optimal shape of the conical component 3 is conical. When the light travels from a denser medium to a less dense medium and the incident angle is greater than or equal to the critical angle, total internal reflection occurs on the surface of the V-shaped teeth 5. The conical shape of the conical component 3 maximizes light collimation. By designing the incident angle to meet the above requirements, light loss can be minimized, ensuring the brightness of the emitted light. The material of the conical component 3 is optical-grade PC material. Figure 2 The specific optical path is shown in the diagram.

[0031] The optical support component 4 is used to support the curved component 2, the conical component 3, and the V-shaped teeth 5. The angle range of the V-shaped teeth 5 is 1.146°-17.062° (determined by the height and width of the V-shaped teeth 5). Because the feature is very small, when light reaches the V-shaped teeth 5, it is first refracted by exiting through the inclined surface. When it encounters the outer surface of other V-shaped teeth 5, it is reflected outwards and continues to refract inwards. The light achieves uniform diffusion by undergoing multiple similar refractions and reflections on the surfaces of several V-shaped teeth 5. This groove with a cut shape not only helps in the transmission of light, but also optimizes the light guiding effect by adjusting the cutting angle and depth, and finally directly provides the light source to the TFT screen.

[0032] The above description, in conjunction with specific preferred embodiments, provides a further detailed explanation of the present invention. It should not be construed that the specific implementation of the present invention is limited to these descriptions. For those skilled in the art, various simple deductions or substitutions can be made without departing from the concept of the present invention, and all such modifications and substitutions should be considered within the protection scope of the present invention.
